Why can laser freckle?
The principle of laser freckle removal is to activate the activity of catabolic enzymes of melanocytes through a certain wavelength of laser to promote melanin metabolism and achieve the effect of freckle removal.
Laser freckle removing therapy
At the same time, the photothermal effect of laser can activate skin fibroblasts and change and rearrange the molecular structures of dermal collagen fibers and elastic fibers, which will not only damage the skin, but also promote the skin to restore elasticity.
However, there are many kinds of spots, and different classes have different treatment schemes, so the treatment effect is naturally different.
For example, chloasma is a common skin problem in all pigmented skin problems, and it is also one of the difficult problems in dermatology. So far, there is no real cure for chloasma.
The treatment of chloasma is mainly skin function repair, supplemented by melanin intervention. At present, the more effective treatment method: by receiving large-spot low-energy Q-switched Nd: YAG laser combined with water acupuncture treatment, and taking drugs orally, chloasma can be lightened and daily attention should be paid to sun protection. You can consult a regular dermatologist for details.
In order to remove freckles, many girls have various tricks, such as freckle cream, freckle cream, bold, and will try the ancestral freckle mask on the rivers and lakes. But is the spot really removed? Not only is it not, but the skin barrier may also be destroyed, making it sensitive, reddish and itchy.
There are still many people who think that the spots on my face are very light and should be easily treated. In fact, the deeper the spot, the shallower the long position, and it is easy to remove. On the contrary, it is a very bright spot with a deep position. Most of them are legendary dermal spots, and they will only get heavier and heavier without interference. This is also the most difficult point to solve ~~ ~
In this case, things with chemical peeling ingredients such as freckle cream are useless and need to be fixed by laser. In the current medical field, laser treatment of pigmentation can be said to be very reliable. For example, sunburn, freckles and chloasma in the superficial layer of facial dermis, as well as dull complexion and dark yellow complexion, can be easily fixed by laser. It can also stimulate collagen regeneration and enhance skin elasticity. Does that sound perfect? As a new medical beauty technology, laser freckle removal is mainly physical therapy, not skin chemical reaction. Through intense pulse selective pyrolysis, the filtered light beam effectively penetrates the dermis layer.
The explosion point of melanocytes is lower than that of normal cells. It is precisely for this reason that pulsed light with a certain intensity can selectively crush melanocytes on the face to achieve the purpose of freckle removal without damaging normal skin. In addition, the wavelength of 590nm also has a good effect on acne and red blood. Deep freckles, senile spots, brown-blue spots on two foreheads and 694nm ruby laser can basically alleviate the spot crisis. There is also a nevus of OTA, that is, one eye and temple are blue. 1064nm C6 laser is effective in treating nevus of OTA, and it is not easy to leave scars.
But! Heizai would like to remind everyone here that although the freckle removing effect of laser will make many girls feel excited, we should be cautious about into the pit. The theoretical basis of all minimally invasive surgery is "destroy first, then build". Laser can crack melanin particles and improve some spots, but it can also cause trauma to the skin. Especially for children's paper with sensitive muscles, even if there are no signs of discomfort, a small number of people are prone to redness after finishing their skin.
People with chloasma should pay more attention. To be exact, there is no medical means to cure chloasma at present, and it can only be improved by photons. Moreover, skin care after treatment is also very important, and strict sun protection is necessary, otherwise it is easy to make the spots worse.
There are also several kinds of "nail households" with spots: Baker's nevus, coffee spots, post-traumatic pigmentation and tattoos. The effect of using laser varies from person to person. Maybe others do it easily, and they may be indifferent to making stains themselves. Therefore, before the treatment, we must communicate with the doctor about the appropriate treatment plan. At the same time, you must go to a reliable beauty agency. Now there are too many laser instruments in the cottage, and too many doctors in the cottage. A little carelessness, any skin burns and pigmentation are commonplace.
Let's talk about it from my own experience ~
I inherited freckles and began to grow on my face, nose and cheeks when I was about 7 years old. I didn't like my freckles since I was a child, and I felt that it affected my image, so I always felt inferior, so I asked my mother to take me to do laser freckle.
Go every three months. At that time, two weeks after the first time, the scab fell off and my face became smooth and white. I am very happy to see that I have no spots for the first time. Later, I went there three times and did it four times.
Laser freckle removal is really effective. It's been a year since the first freckle removal, and my face is much whiter and there are almost no spots. Only in summer, when the sun shines, some small freckles will recur for a while. I plan to do it again when I have time to get rid of the new sporadic spots.
I don't have much feeling that my skin will become thinner and more sensitive. My own skin is very sensitive, and I didn't say it would be more sensitive after freckle removal.
It's just that it takes a recovery period of one to two weeks to do laser freckle removal, so people who want to go to school or work don't have that much time.
If you want to know whether laser speckle removal is effective, you must first look at what kind of speckle you want to remove. Because, like all treatments, laser freckle also has its adaptive population and contraindications.
Laser freckle removal is most suitable for removing freckles, sunburn, senile plaque, zygomatic mother spots and other spots. Because these spots are structural spots with increased melanocytes, surgical laser can improve them and the effect is better.
If there are not many dark spots, but the skin color is uneven due to sun exposure, laser can also improve;
In addition, acne marks and sunken scars left by acne, as well as various skin aging symptoms caused by photoaging, such as rough skin, large pores and superficial wrinkles. It can be improved by the deep effect of laser on the skin.
However, it should be noted that although laser freckle has a good effect on pigment spots, it has a general effect on chloasma.
Because chloasma belongs to functional spots, it is not the increase of melanocytes, but the constant secretion and accumulation of excessive melanin by epidermal cells.
At this time, if laser treatment is used, it is easy to damage pigment cells due to excessive or frequent application of energy, and local anti-black or anti-white polarization will appear. (6 1)
Whether it is effective or not depends on your own feelings.
I really feel good within a week after finishing the laser, but there is anti-black phenomenon behind, and the doctor won't mention it to you before. If this anti-black phenomenon is not handled well, the spots will rebound and the consequences will be really serious.
Many people's skin becomes thinner because they don't do laser freckle, which leads to sensitive skin irritation and lack of sun protection. They really ruined their appearance. You can find the news in the hospital news.
Those doctors clap their chests to make sure the effect is safe before doing it, but do you dare to let him write a guarantee? Surgery is a risky thing. No matter how small the laser is, it is also an operation. Take all the risks yourself. Don't do it unless you have to!
If you really want to remove freckles, I think the method of external application is more reliable. Because the method of internal adjustment is too slow to take effect, the stain is mainly due to the deposition of melanin in the basal layer. If the freckle product is reliable, you can bring these melanin out! But the choice of products is also very important. You can't choose those that remove freckles quickly. Something must be wrong, believe me.
Really effective freckle removing products, such as repairing a three-piece suit, are cleaned first, then adjusted and then raised. If melanin doesn't have this effect, then it can't be said that freckle is complete at all.
Laser freckle is effective quickly, but it is not a permanent cure, which requires high technology for operators, and there are problems such as subsequent blackening and postoperative sequelae.
The biggest headache for people with long spots is the spot that they can't get rid of despite their efforts. Laser freckle can fade spots immediately, but the root cause of spots is endogenous problems, which will regenerate later. Therefore, laser freckle should be done regularly.
Laser speckle reduction surgery is to promote the dispersion of spots by irradiating light with certain energy on the skin. Different skin has different energy tolerance, different pigments need different irradiation energy, and the energy is biased, which not only hurts the skin, but also may cause the problem of rapid blackening after operation, so the technical requirements for operators are quite high. Do it in a formal medical and aesthetic institution as much as possible, and don't do it in informal channels for the sake of cheapness.
After laser speckle removal, energy will do some harm to the skin and remain in the skin, making the skin sensitive and photophobic. Usually, we should do a good job of sun protection, not only to reduce direct sunlight as much as possible, but also to use sunscreen every day, and to reduce the use of skin care products containing vitamin C and various acids during the day.
Laser speckle reduction is effective quickly and obviously coexists with risks. Doing it in a formal institution may cost more, but it can reduce the risk. It is you who spend money, you who benefit, and you who suffer ... so you must weigh the pros and cons before the operation. ...
Laser speckle is really effective.
Just sunscreen after freckle removal, have a light diet and be in a good mood. Don't stay up late, or you will grow new spots. Thank you for coming!
Not recommended. Laser freckle has side effects.
The correct way:
Fading spots needs to go deep into the skin muscle layer to inhibit the growth of new spots, break the chain of spots formation, and gradually break up the melanin accumulation on the skin epidermis, gradually decompose spots into smaller and smaller melanin particles, and eliminate them from the body with the help of the skin's own effective melanin metabolism system. This is the real root cause to improve the spot problem.
Laser freckle removal or "ointment" and "peeling" are both quick-acting and palliative methods, but only for the spots on the skin surface, the side effects may lead to thinning, fragility and sensitivity of the cortex, and once the spots rebound, it will only be more serious.
What harm does laser freckle do to the skin?
Scar problem:
Laser freckle will leave scars. If these scars are recovered in time, they will not be visible after complete recovery, but there will also be some special accidents that lead to obvious scars on the skin. For example, the operator's inexperience, inability to grasp the depth of treatment, skin tissue damage or untimely machinery and equipment will all lead to obvious scars on the face.
Burn problem:
Laser freckle removal is to irradiate melanin in the skin with light beams, so as to achieve the purpose of crushing melanin. However, if the beam energy used in the operation is too high, the skin will be red and swollen, and generally it will disappear soon. If it doesn't disappear and there are pain symptoms, it is a burn.
Rebound problem:
Laser freckle removal can only remove the melanin existing in the current skin. If you don't handle it properly after operation, such as not doing a good job in sun protection and eating some foods with high pigment content and irritating foods frequently, the melanin in the skin will become active again and the spots on your face will rebound.
Everyone's long-term living habits and nursing habits are different, and the causes of pigmentation problems are also different. Therefore, it is the safest way to take measures according to your actual situation. I hope my answer can help you. If you don't understand, you can leave a message in the comments section. I will reply one by one.
Laser speckle removal is the use of high-intensity instantaneous energy of visible light. Lasers with different wavelengths will be absorbed by special colors or pigments in the skin. For example, freckles absorb green light easily. The laser with different wavelength energy has different effects. At present, there are as many as 7 or 8 kinds of lasers used to treat skin problems.
1. Laser freckle removal is more accurate, and light yellow freckles still have obvious curative effect.
2. After laser freckle removal, not only facial blemishes-freckles can be removed, but also the characteristics of laser can be used to improve skin quality.
3. Laser speckle removal is an ideal speckle removal technology. The surgical incision is small, and the effect is quick and non-invasive.
It is suggested that beauty seekers choose to go to some large regular plastic surgery hospitals for surgery, so that the postoperative effect will be more ideal. In addition, beauty lovers should do a good job of postoperative care, which is helpful to the recovery and effect of surgery.
Theory: Needless to say, many people have already answered.
Effect: the effect on freckles is not bad, mainly depending on the skill and experience of the operator, and other spots are completely unsolvable.
Danger: whether it is laser, picosecond, chemical peeling, liquid nitrogen freezing technology, etc. Freckle removal is only the first step, and the pigment decomposes and falls off. Freckle removal is divided into four steps: the first step, pigment decomposition, the second step, skin repair, the third step, pigment reflux control, and the fourth step, maintenance. Laser freckle removal is only the first step, and the control of late repair and pigment reflux is weak, so the skin damage can not be repaired in time, which may lead to deeper pigment in the spot.
